PDFs created from draft files are not showing shaded views

I am trying to create PDFs of assembly drawings that have shaded views. I'm using Adobe XI Standard. When I print the views using the PDF driver, the preview shows the shaded views, but the end result just has non-shaded views. Any ideas or settings I could try?

Well, it turned out it was the cryptic registry entry that made everything work. I had to refer back to Sean Creswell's post back in February of 2014 to get. I went into DBUG in the ST108 registry and created a new DWORD key with STRETCHMASKBLT with 0. I tried using 1 and it took forever to make the PDF.
